He was also known for his autobiography, which related the history of Japanese-occupied Singapore and was criticized by many researchers and Singaporean residents for his self-praise and for alleged lies and distortions of many historical facts.

As a student, he was interested in socialism, secretly reading the works of Karl Marx and Friedrich Engels, a serious offense which got him expelled from his high school in Kyoto.

[15][16][17] After the Pacific War began on 7/8 December 1941, Japanese residents of pre-war Malaya had moved to the Purana Qila internment camp.

[19][20][21] He participated in the Sook Ching Massacre as one of the staff who tempted English-speaking Chinese leaders such as Lim Boon Keng, who was captured during the "great inspection", to cooperate with the Japanese Military Administration (JMA).

While the schools were still inactive, for the ceremony of The Emperor's Birthday scheduled to be held on 29 April 1942, Shinozaki taught children to sing Kimigayo and Aikoku Kōshinkyoku to please General Yamashita.

[39] According to his autobiography, he met with Shigenori Tōgō, Minister of Foreign Affairs, who rewarded his long imprisonment with "a thick wad of cash".

[41] In this period, the Welfare Office issued "thousands of Good Citizen's Ticket" which was necessary to travel to the suburbs of Singapore (that was not to rescue the people from the threat of Sook Ching).

During the meeting, Gaus was blamed by Shinozaki for his opinion, which was based on Melayu Raya's attempt to disturb the unity of Malayan society.

Shinozaki angrily requested Gaus to cooperate to maintain the unity of Malayan society because the "Holy War" was ongoing.

[47][48] Shinozaki told them to look for participants, advertising that the "settlement" was free from Kempeitai monitoring and was abundant with soil and crops, that it was utopia.

Then, they sent the Chinese and Eurasian residents that applied for the plan, who were seen as "hostile" to the JMA, to Endau ("New Syonan"), where sufficient irrigation facilities was lacking until re-development by Japanese POWs in 1946, and Bahau("Fuji-go"), where Malayan policemen were always monitoring the "settlers" and many died from malaria.

Before their very eyes lay not fertile valleys that could be profitably tilled, not the Utopia that Shinozaki and company had lectured them on, not wells that produced sparkling water within a few feet of the earth's surface.

Fuji-go was nothing more than a clearing four miles square in extent and not even that, for the giants of the forest that had been felled lay exactly where they were when cut down.Bishop Devals got sick and died from overwork in January 1945 at a hospital of Seremban.

[60] In 1944, as the reality of the "settlement" (few actual benefits, need to wait for food from Syonan, and rampant malaria) was orally spread to Singapore, people applying to be "settlers" declined sharply.

[61] Shinozaki, in his autobiography, didn't refer to such situations and blamed the MPAJA saying that they disturbed Endau and Eurasians by being lazy in Bahau.

Later the people will understand the good intentions of the authorities and have cause to thank them.On 26 July 1945, Shinozaki was appointed to Sub Chief of Auxiliary Police Force.

[67] However, according to some newspaper articles at that time, Shinozaki was one of a hundred Japanese residents of pre-war Malaya who had applied to remain in Singapore.

Because he was ruled guilty as a spy in 1940, there was little hope of approval, so he cooperated with the British Field Security Force by prosecuting his colleague, a member of the Kempeitai as a war criminal, to obtain forgiveness for himself.

[79] From 28 August 1972 to 5 October 1972, his autobiography was translated into Chinese by Chin Kah Chong, published serially on Nanyang Siang Pau.

[86][87] On 1 November 1972, on Sin Chew Daily, Chuang Hui Tsuan wrote an article which criticized Shinozaki's self-praising in his autobiography.

Anybody who lived through that period knew that the Japanese Army, after occupying Malayan City, set up a "Security Preservation Committee" or similar organization, so Singapore couldn't be an exception.

[93] In November 1974 on Science of Thought [ja], a Japanese journal, Hiroshi Tanaka introduced the series of articles from Singaporean Newspapers which criticized Shinozaki's autobiography.

[94] In May 1975, a writer of New Nation doubted the credibility of Shinozaki's autobiography when he had written that 10,000 Japanese prisoners had died in Singapore, in British PoW camps after the war.

Though Chuang died in 1974 and Hsu died in 1981, Chua Ser Koon continued editing and in 1984 the book titled Xin Ma Huaren Kangri Shiliao (Malayan Chinese Resistance to Japan) 1937-1945 was published to tell the experiences of the Singaporean citizens who lived through the period of Japanese occupation and to tell the "true history" to the next generation.
